APPARATUS FOR FEEDING PAPER SHEETS.

7 Application filed September 24, 192?,Serial No. 221,835, and in Germany November 5; 1926.

This invention relates to an improvement in or modification of the apparatus for feedingpaper sheets as described in our prior U. S. Patent, No. 1,649,401, and comprising aplurality of conveyor ribbons. In

said apparatus, the sheets are placed in;

spectively and at its upper end on longitu--' dinal rails by means of guiderollers thereon. Said rake forms an inclined plane, from which the sheets can easily slip off and be taken up by the conveyor ribbon. During the advance of the sheet-loaded rake, other similar rakes with fresh sheets thereon can be applied, so that an uninterrupted working of the apparatus is ensured.

The same arrangement of sheet-feeding rake can be used on the uppermost convey-v or ribbon, if desired.

The accompanying drawing illustrates the improvement: F ig.- 1 is aside view thereof, as applied to the lowermost as well as to the uppermost conveyor ribbon; Fig. 2 is an end view thereof, and Fig. 3 shows a detail thereof in a side View on a larger scale.

. Beyond the conveyor ribbon 27, which is guided over rollers 28', 29, the table plate 30, on which bears the upper part of said ribbon, carries on each side thereof two fixed brackets a connected by a rail b that is directed parallel to said ribbons. The

. rake to be put on said rails consists of a spindle 0 with loose guide-rollers d mount ed at its ends and prevented from axial displacement thereon by means of a set-ring e on each side thereof, said rollers. being grooved and engaging with, its groove 7 freely over the rails b so that the spindle cannot be displaced in lateral directions. The spindle 0 carries a plurality of Weakly curved rake members 9 arranged thereon at equal distances from each other and adjust,- ably fixed thereto by means of their integral veyor ribbon.

in which said rake consists of a lugs k and setscrewsc' with counter-nuts i g The lower end of said rake bears upon the.

table plate andengages in groove 80 therein, preferably at the places intermediate the conveyor ribbon parts 27, while the spindle c bears with its guide-rollers cl on the lateral rails-band can be moved along the same. The front ends of the two outer? most rake members g bear upon the two outermost narrow conveyor ribbon parts 27 a and are for their intimate contact with the,

latter fitted with pointed counter-hooks g engagingin the fabric ofthe conveyor ribbon without damaging the same.

If it is desired to supply sheets directly to the uppermost conveyor ribbon 17, which is guided over the rolls 16, 3'2 and providedwith a table plate 19 underneath its upper I i part, the same arrangement of sheet-feeding rake can be used. thereon.

Normally, however, the sheets are fed from the lowermost conveyor 27 to the uppermost one 17 by means of an intermediary conveyor 26 guided over rolls 24, 25.

What we claim, is 1. In an apparatus for feeding paper sheets, the combination with a conveyor ribbon and a table plate underneath its upper part, of fixed rails located on both sides of said table plate beyond said conveyor ribbon and directed parallel to the latter, a detachable weakly curved sheet-reception rake forming an-inclined plane and during its use guided at its lower end on the con- 4. In an apparatus as specified in claim I 1, pointed counterhooks at the lower end of said rake for engagement. with said con- 5. An apparatus as specified in claim 1, plurality of adjustable rake members. r 1 T In testimony whereof We -have hereunto set our hands.
